For the first time, NASA scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra.

NASA Astrophysicist Amber Straughn will give a talk about the search for Earth-like exoplanets to launch the 2017 season of Family Astronomy nights at the Intrepid Sea, Air & Space Museum on Friday, July 14.
